All Activity

I don't work in post, but I'm currently bringing a documentary through post as a director and we have been 100% in DaVinci Resolve. If you use it for both picture and sound (the Edit & Fairlight tabs), there's no conform step going back and forth, which makes it more possible to go back and do picture edits after picture lock and during the sound edit. It's also cloud-based, which makes it possible for video and audio to work remotely without shuttling things back and forth. Not saying that's an ideal workflow, and it would presumably be a big decision for your client to change post programs, but maybe it could help?

If there was both genny and local power available, and you really did need to power from something other than your own DC system, I'd want a pretty good reason to not use the local (wall) power. I've been really hosed by relying on genny power, even when the electrics were friendly. You don't see cameras running on AC, right?

I have an editor friend whom i do production sound recording for on projects as well as audio post with pro tools. in a perfect world i get pic lock and audio post as one normally would. Lately he is getting projects where he wants to present to client as "this is what it could look/sound like" and we are struggling finding a modern workflow to make both audio and video changes along the way as client makes decisions. I used to have great success with EdiLoad to track changes but the different worlds of video edit and audio post seem to always work against me. Is a possible solution for this - I subscribed to adobe to get Premier or Audition and work with picture edit in a cloud based environment until we reach picture lock? curious how others in a similar PSM and Audio Post situation currently approach this. -Ken

Regarding your first scenario, it's not clear to me what you mean by "touches....something on the house power". I assume you mean they are in contact with house ground and the genny ground and you are concerned about the differential voltage being harmful. The following suggests that that is not a possibility if the practices called out by Local 728* are followed. It states "When mobile generators supply power to location production systems IN ADDITION TO the building's electrical system, the generator's grounding connection SHALL BE BONDED TO THE MAIN BUILDING GOUNDING ELECTRODE SYSTEM AT THE SERVICE." (Their caps, not mine) *Local 728 paper entitled: Basic Electrical Safety Precautions for Motion Picture and Television Off Studio Lot Location Productions . Published August 01, 2000.

Why would you need an inverter?

I'm curious too ... seems like a good question for testing the knowledge of your gaffer...

Most of my carts used equipment that ran on DC power supplies, ie were made to run off batteries (I know, quaint). The solutions I used for powering them were at first always big gel cel batteries (even on a stage) with bespoke DC-DC convertors, then later the excellent old PSC "Cart Power' box (AC to DC, with power distro). The Cart Power had a 3-pin AC plug, and I don't recall any issues with using its U-ground really ever. My power issues were never with properly designed professional audio gear, they were always with flaky cheap monitors, low budget powered speakers, work lights or other lesser gear that did not have good power design and ran off wall-warts.

Good questions

Careful you don’t blow up your RF Explorer front end connecting it directly to a transmitter. Not sure what the max signal input is. May want to at least start with the lowest transmitter power. Good thinking though!

Basically, adding power to a cart is like plugging in a big power strip on your cart. Yes, that should probably be a 3-prong grounded cable. But should I bond that ground conductor to the metal cart and rack, or should I actually try to insulate against grounding anything (In the US, if that matters, and it must be within NFPA/NEC codes. I have a codebook but have no idea what section it's in because filmmaking uses a lot of standalone generators.) I can see issues either way. One issue is if it's on genny power and someone touches both the grounded cart and something on house power, there could be a high enough voltage bias between grounds that could shock. But if you have failing equipment on the AC side, it might be safer to have the cart grounded properly to the genny's ground, with a proper ground wire on any AC equipment. A second, related question is if the cart has a 120v inverter on it, like a car inverter, should chassis/neutral be bonded to the cart, too? These generally do not have a connected ground, but I believe they can be chassis grounded and that will act as 0V to bias the waveform around it. (Yes, I realize it is somewhat redundant to have an inverter plus an active genny powering it, but an inverter can run off your battery to power any AC devices without worrying about whether you lose power.)

Thanks for the advice, I finally figured out a way to do it from things I already have :). I didn't measure the attenuation exactly, but I was more interested in comparing some cables with each other and whether there was a bad one... I used the RF explorer and a bodypack transmitter. I connected the measured cable to the RF explorer and connected the antenna output of the transmitter to its end and measured the cables with each other like this...

SMall delay is actually beneficial for video monitor delay

I’ve been using them for several months in conjunction with my Comtek receivers. They sound a bit better to me than the 216s. The squelch seems to be better too. The only negative I’ve noticed is that there is a (not terrible but) noticeable delay compared to the comteks.

I am also interested in your report, it should be a good microphone!

I just ordered one from Trew. I'll report back after I use it in the field. Thanks for the advice.

100% correct. So if you're traveling to a spot, the Macbook Pro charger you already take will work. No need to pack multiple power supplies.

Thanks very much for this recommendation, I will give a reminder!

Are you referring to record stores? If so, in Copenhagen, I like to go to "Sound Station" and "Mint Records". Also, I like to grab a beer at Ørsted Ølbar as they usually have an LP spinning and last time I was there, they even had their reel to reel deck.

All you need for that is the calculator, or to look at the cable datasheet. That being said, +1 for the nanoVNA. Being able to measure the effectiveness of your antennas over frequency is very useful.

Music shops in Denmark in Copenhagen and Malmö? Please recommend, as we are going to Copenhagen before Christmas in next week to see The Little Mermaid.

Yes, it can do much more than we would generally be interested in, Smith chart for example. You do have to be careful with the settings and calibration to be sure you’re getting good data but I love it. I’ve used it to measure SWR of my antennas to gauge that they’re working correctly. I confirmed a bad Comtek phaseright this way. Of course, you could also determine this the normal way by the fact that it’s working like shit but it’s nice to be able to dig a little deeper and check all the components. The other nice thing about measuring antenna cable loss with the nanoVNA is that it plots the data across a specified frequency range so you can easily see what the loss is for your target frequencies. For example, a cable that has 12dB of loss at 600MHz might only be about 6dB at 200MHz or on the other end maybe more like 16dB at 900MHz. The fact that you can do all this with reasonable accuracy on a <$100 device is amazing.

The Octopus looks super intriguing! But yes, the NanoVNA will do nicely with very little investment. One benefit of going this route is you can easily measure end-to-end loss through devices, any interconnected cables, splitters, barrels, etc. While it can get more complicated (measuring phase, etc), I usually just pay attention to the attenuation trace.

Here: https://rycote.com/microphone-windshield-shock-mount/super-softie/ But I have no experience with it, I just considered buying it, but I decided that I would not go into rain and I have this freedom.

I would take everything that rycote says with a grain of salt.
